Title: Measuring device for internal pressure of mold
Inventor: IMATOMI YOSHIYUKI
IPC: B29C45/76
Filed: 1990-05-29
Abstract: PURPOSE:To prevent a pressure pin from slipping off when a pressure sensor is removed by providing an enlarged section encircled with a first and a second ejector plates of a pressure pin on the position adjacent to the pressure sensor and a projected section extending from the enlarged section through the second ejector plate. CONSTITUTION:When pressure is measured by inserting a pressure sensor 38, the end surface of a pressure pin 55 is brought into contact with a pressure sensing section 61 of the pressure sensor 38, and when resin is flowed in a mold, the resin is brought into contact with the end section of the pressure pin 55 and resin pressure is transferred to the pressure sensing section 61 through the pressure pin 55 and the pressure is sensed. A section (a) between an enlarged section 59 and the second ejector plate 52 is set in a manner that the enlarged section 59 is not in contact with the second ejector plate 52 in the case that the resin pressure is not received by the pressure pin 55. In the case that the pressure sensor 38 is removed and the pressure is not measured, the pressure pin 55 is not slipped off as the enlarged section 59 abuts against the second ejector plate and stops even if the resin pressure is applied to the pressure pin 55.

Title: Screw for injection molding machine
Inventor: FUJIWARA YOTARO
IPC: B29C45/62
Filed: 1990-05-29
Abstract: PURPOSE:To carry out color change in a short time, greatly improve the working time and upgrade the molding cycle by forming a screw channel on the resin material feeding side deeper than a screw channel on the molten plasticized resin discharging side and reducing the width of screw channel on the feeding side gradually toward the discharging side. CONSTITUTION:As the width and depth of a screw channel 14 on the material feeding side is reduced gradually toward the B-B, C-C and D-D section, unmelted resin is pressed to the inner wall surface of a cylinder 6 correspondingly to the reduction of section area passing through, and scraped into a sub-flight 3 while being melted successively starting from a contact surface of the cylinder 6 in the resin feeding screw channel 10 by the heat received from the inner wall surface of the cylinder 6 and the shear heat development generated by the relative slip with the inner wall surface of the cylinder 6 following the rotation of the screw, and moved beyond the sub-flight 3 toward a screw channel 11 on the molten plasticized resin discharging side. Said completely molten resin moved to the screw channel 11 on the molten plasticized resin discharging side is moved to the discharging side following the rotation of the screw and fed into a cavity formed with both of male and female molds. color change, therefore, can be completed in a short time.

Title: Manufacture of semiconductor non-volatile memory

IPC: H01L29/788
Filed: 1988-06-06
Abstract: PURPOSE:To prevent the deterioration of quality due to the high-temperature process of the oxidation of a control gate in a post-process, and to increase the number of rewrite by using an oxide nitride film as a tunnel insulating film. CONSTITUTION:Since an oxide nitride film 6 as a tunnel insulating film is formed by oxidizing a thermal silicon nitride film 5 having extremely slow oxidizing velocity for a prolonged time at a high temperature, the quantity of the film 6 is improved, thus realizing the reduction of the breakdown of the tunnel insulating film due to rewrite. A control gate oxide film 8 is shaped by thermally oxidizing a floating gate electrode 7 at the high temperature. Since the floating gate electrode 7 is composed of polycrystalline silicon in the process, the gate electrode 7 must be manufactured by a high-temperature thermal oxidation process so as to maintain the quality of the film on the gate electrode 7, but the quality of the tunnel insulating film is not deteriorated even when there is such a high-temperature thermal treatment process because the tunnel insulating film consists of the oxide nitride film 6. Accordingly, high electric-field stress is increased, and accidental breakdown due to rewrite can be prevented.
